Filter drier - structural elementrefrigeration units, which is used to remove moisture from the refrigerant. The device is installed between the capillary tube and the condenser, protecting these parts from solid blockages.
From the condenser side of the air conditionerThe filter drier contains a grid with large cells. It serves to protect the system from the ingress of zeolite granules. There is also a mesh on the side of the capillary tube. Its small holes hold small particles that accumulate in the liquid refrigerant as it passes through the split system.
Replacement of the functional element may be required in the development of its life, or in the event of depressurization of the air conditioning system. The following tools allow you to cope with the task:
The work is carried out in several stages. To start with the help of a burner and a pipe cutter, the old filter drier is dismantled and must be replaced. The surfaces are then carefully cleaned to attach the new device. Finally, the drying element is soldered into place, the system is evacuated by means of a pump, after which the refueling system is refilled.
Quite often, the presence of garbage in the system cancause a clogging of the new filter-drier and the capillary tube of the air conditioner. Therefore, after performing the work on replacing the element, it is necessary to maintain the main components of the freon loop.
Filters-dehumidifiers have a limited resourcework. Therefore, the masters introduced such a requirement as their mandatory replacement. To determine how long the filter drier is capable of operating, it is sufficient to carefully study the technical documentation when selecting it.
Most manufacturers of air conditionersit is recommended to perform the replacement of the dehumidifier each time when the system is serviced, even if there are no failures in the operation of the element. The cost of the filter is negligible. Therefore, it is worthwhile to listen to such advice, which will avoid more embarrassing waste in the future.
As can be seen, if there is a specializedtools and equipment, the replacement of the filter-drier is not a very difficult task. At the same time, trust the work better to the master who already dealt with this kind of tasks. Independent dismantling of the filter-drier can lead to damage to the compressor, other determining nodes of the system.
